I'm kind of a newbie around xtext, xpand and xtend, I'm trying to use it in a modernization process involving CORBA's IDL.

I've succesfully imported my IDL metamodel in the form of an .ecore file (inside a project called IDLMM) in my xtext t2m transformation, and now I'm trying to use the generator (xpand) to generate code. The problem is that, although I was able to import that .ecore metamodel in the xtext grammar (import 'platform:/resource/IDL-MM/IDLMM.ecore' as IDL), I don't find the way to import that same metamodel in the generator project!. Could anyone bring some light around this surely naive problem?
